as disclosedV in Patent No.1,560,293, one

sect-ion extending along 'each wall' of theA length` of the wall;

Each 'section of y wallcfthe building comprises a wall form building,and each i section V'ma'ybe the entire "or: mold1 proper `includingv'the inner` and the apparatus lfor vone outer side plates 10 of sheetmetal, wood ory other suitablematerial. Said plates are of suitableheight to define one course of the wall' and said plates may be insections se-4 cured together end toend in any suitable manner.

The side plates 10 are supported by hangers 11, which are of. angle ironas shown, and which are bolted or otherwise secured to said plates Vwiththe upper terminals of WALTER THEoDoR EELS, oF `Naw YORK, iv. y.,AssiGNon To FELSTQNE FIREPROOF,

said hangers projecting above the upper edges of the plates forconnection with the yokes or cross bars 12 .extending trans` verselyover the plates at suitable intervals longitudinally of the form. Theupper ends ofthe hangers 11 are pivoted by means of bolts 13 to theyokes 12, said yokes having longitudinal Series ofv apertures 1li toreceive said bolts, whereby the plates 10 may be i spaced apartdifferent distances for producing walls of differenttliicknesses. kTheyokes 12 preferably have numb-ers or other indications above theapertures 1st in order that Vthe hangers may Lbe readily adjusted forproducing a wall of desired thickness.

The yokes l12 are provided at their opposite ends with arms 15 extendingdown wardly at obtuse angles, and means are provided between said arms15 and hangers 11 for swinging the plates 10 toward and away from oneanother. The arms 15 have Sil circular heads 16 at their `.loweriendsprovided with diametrical apertures 17 there,`

through in which screws 18y are swivelled circular wallsof the heads 1Gto permit the screws 18lto swing in the vertical planes of the yokes 12.The screws 18 have cranks 18" above the heads 1G for convenientlyrotating said screws, and vlhe lower terminals of the screws arescrew-threaded within sleeves or velc'ingatedv socket nuts 2() whichhave their lower ends pivoted, as at 20, to the lower terminals ofthehangeis 11.` Thus, by rotating the Screws 1S,`the plates 10inay beswung toward and away from one anV other, andlthe screws S'may'oscillatein the apertures 17 which Vare siiiiiciently largeto permit ofsuch oscillation; The screws 18` and sleeves or nuts4 2O provideextensible and' arms l'enable the plates 10 to be swung for rotation,nuts or collars 19 being secured away from and toward the wall withconsiderable torce.

The form or mold is supported directly and solely from the wall which isunder construction, without usinga special framework, therebyproviding asimple and convenient construction, to save time and expense. F or thispurpose, vertical screws 21 are provided and serve three purposes,namely v the form or mold proper is supported by the screws which aresupported. from the wall under construction, the screws are employed forraising the form or mold as cach course 1s completed, and Ythe screwsserve to guide the lorm or mold vertically so that the wall is plumb.Each screw has a smooth lower terminal 22, and has a head 23 ot' squareor angular :torni at its upper end, and the thread of the screw has itsconvolutions spaced apart in order that the screw may be unscrewed fromthe concrete or other plastic composition as will hereinafter more fullyappear'.

Each yoke 12 is supported from one ot the screws 21, and for thispurposel a nut 24 is litted snugly on each screw, and is swivclled tothe intermediate portion ot' the corresponding yoke 12 between thehangers r11. The nut 24 is journaled for rotation' within a bearing withwhich the yoke 12 is provided, one hall or section 26 ot' the bearingbeing integral with the yoke, and the opposite hall' or section 27 beingsecured to the section 26 by bolts 28 or other clamping elements, saidsections 2G and 27 complement-` ing one another and embracing the nut24. 'llhefnut 24 has a lower flange 30 abutting the' lower end of thebearing 26-27, and the nut 24 is provided near its upper end with anintegral ratchet wheel 31 seating on the bearing.

In order to rotate the nuts 24V oil one section of the apparatus, alever32 is mounted for rotation on the upper end portion of each nut 24,being swivelled and confined between iheratchet wheel 31 and a retainerring 25 secured on the nut. A spring-pressed pawl or dog 33 is carriedby the lever 32 at the lower surface thereof to engage the ratchet wheel31, in order to rotate the nut. 24 in a direction to climb upwardly onthe screw 21 when the lever 32 is oscillated.

The levers 32 of each section'of the ap-r paratus are connected by a bar34 so that the levers of one set may beoscillated simul-l taneously, tocause all ot the nuts 24:01 one section ot the apparatus to climbsimultaneously upwardly on the screwsy 21.

The oscillation of each lever 32 is limited by means of a stop bar 35extending' below the lever 32 and having depending stop lugs 3G at vitsends to contactwith the yoke 12, said bar 35 being 'secured to the lever32 by means of bolts 37. Y

In order to prevent the` reverse rotation the course 43.

of the nuts 24, va hole 38 is drilled in each bearing 26-27, preferablyin the section 26, and a ball 39 is disposed in said hole so as to wedgebetween the nut 24 and opposite wall of the hole 38,A as seen in Fig.(5, to prevent the reverse rotation of the nut, but permitting said nutto rotate in a direction to move upwardly on the screw 21. A coiledspring 40 is confined beween the ball 39 and an adjusting screw or plug`41 screw-threaded into the hole thereby holding the ball 39 in place.

The apparatus is used as follows: The lower ends 22 o1 the screws 21 areinserted in recesses or holes provided in the base or foundation 42, asseen in Fig. 4. The screws 18 are then rotated so as to move the 'plates1() to vertical position, and the screws 21 are then adjusted so as tobe plumb or vertical with careful accuracy, in order that thev wallwill' be started upwardly plumb. The concrete or grout is then pouredbetween the plates 10, with the form or mold heldl firmly in position,thereby producing the lirst course 43 on the base or foundation 42.lVith the form in starting position as seen in Fig. 4, the plates 10contact at'their lower edges with the base or foundation and the nuts 24are located intermediate the ends of the screws 21, with vthe screwsprojecting upwardly above the yokes 12. 1V hen the lirst course 43 hasbeen poured and has set suliiciently so as to firmly .support the screws21, the form is then raised so as to enable the next course about to beformed. The nuts 24 are rotated by reciprocating the bar 34, so thatsaid nuts climb upwardly on the screws 21, said screws having theirlower portions embedded in The bars or yokes 12 and plates 10will beraised with the nuts 24, the screws 18 having been previously rotatedsogas to swing the plates 1() away `trom the opposite surfaces ot thecourse 43. This permits the i'orm to be raised conveniently wit-h theplates 1() spaced from the concrete.

VlVhen the nuts 24 reach the heads or stops 23, the screws 18 arerotated so as to swing' the plates 10 toward one another, as seen in Fig. 2, with the lower edge portions of said plates overlapping the upperportion of the course 43. The concrete, plastic composition or grout forthe second course is then poured between the plates 10 of the lorin.thereby producing the second course 44 on the course 43, with the screws21 embedded in both courses 43 and 44. After the course has set orhardened sufficiently, the torni isagain raised to position it for thethird course. The screws 18 are lirst rotated to swing the plates 1()away from one another out of contact from the course 44, and the bar 34is then reciproeated to rotate, through the ratchets, the nuts 24. Saidnuts contactlingwiththe stops or heads 23 will prevent.

.llU

the nuts from climping upwardly further on the screws 21, and the screwsare therefore compelled to rotate with the nuts. The screws 21 beingrotated will be unscrewed partially from the wall which is underconstruction. Thus, as seen in Fig. 3, the screws 21 are unscrewed fromthe course 43 but remain in the course 44 when the plates 10 have been`raised sufficiently to position them for the productioirof the next orthird course. The plates 10 are then again swung toward one anot-her to'bring their lower edges into overlapping relation with the course 44,and the operation is repeated as hereinbefore described. The screws 21remaining in the course 44 will support the screws and orm from saidcourse. In this way, the screws are always supported by the last courseand remain therein until the next course has set sufficiently, at whichtime the screws are unscrewed for the next operation. The screws thustiavel upwardly in the wall under construction to continually supportthe form fromthe wall, to move the form upwardly, and to guide it forvertical movement so that they wall will be plumb. It will be noted thatthe screws have at least their lower halves embedded in the concrete inorder to prevent the screws from inclining out of plumb, and thewall'will therefore be built up vertically provided the screws 21 arestarted in true plumb positions. As the screws move upwardly with thebuilding up of the wall course after course, vertical holes or passages45 are left in the wall. These passages are not objectionable and may beused for ventilation, electric wires, or the like, inasmuch as inletsand outlets may be drilled in the wall to said passages 45. Bycompletely unscrewing the screws Y Q1 from the last course the apparatusis `quickly removed from the wall. It will also vbe-noted that as thewall progresses upwardly it is entirely unobstructed below the form, theapparatus being conned vto the upper edge portion of the wall. "This en-Y ables other work to be done on oradjacent to the wall as the wall isbuilt up. l

The screws 18 at each side of the form or mold may be operably connectedso as to be operated simultaneously. Thus, as shown inFigs. 7 and 8,sprocket wheels 46 are secured on the upper ends 'of the screws, and an.endless chain 4'7passes over said sprocket wheels for simultaneouslyrotating said wheels and the screws 18.A Guards 48 'for thecliainstraddle the wheels 46 and are pivot-ally mounted on thescrewslS, toprevent the chain slipping ott'V the wheels.

Having thus described the invention,what is claimed as new is Y. 1. In awall molding apparatus, a
